About Converting Terahenrys to Gigahenrys
Terahenry and Gigahenry both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Terahenry is 1000000000000 henry units, and gigahenry is 1000000000 henry units.
Formula
gigahenrys = terahenrys × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 terahenry equals 1e+12 base units, and 1 gigahenry equals 1000000000 base units, so dividing one by the other gives the direct terahenry-to-gigahenry factor of 1000.
Simple example
1 TH × 1000 = 1,000 GH
1 terahenry = 1,000 gigahenrys.
Real-world example
120 TH × 1000 = 120,000 GH
120 terahenrys = 120,000 gigahenrys.

Frequently asked questions
How many gigahenrys are in 1 terahenry?
1 terahenry equals 1,000 gigahenrys, using the exact defined conversion factor rather than an estimate.
How do I convert terahenry to gigahenry?
Multiply the terahenry value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert gigahenry back to terahenry?
Use the reverse factor: 1 gigahenry equals 0.001 terahenrys. You can also use the swap control in the converter above to flip the direction instantly.
What is a terahenry?
Terahenry (TH) is a unit of electricity.
What is a gigahenry?
Gigahenry (GH) is a unit of electricity.
Is the terahenry to gigahenry conversion exact?
Yes. Both terahenry and gigahenry are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
